Opstal Estate is a 7th generation family owned farm, located in the picturesque Slanghoek Valley, between the beautiful Badsberg and Drakensteyn mountains. Block R on the farm, the Chenin Blanc, spans 2.5 ha and was planted in 1982 by the 6th generation farmer Stanley Louw. This deep sandy loam soil has got very good natural drainage. In 1987 this particular block won the South African National Vineyard Block Competition and to this day we still use the term “wen blok”. From this wen blok, Attie Louw the winemaker, crafts the famous Carl Everson Chenin Blanc, named after the 4th generation farmer, our great grandfather.
